AMP validation: The attribute '[type]' may not appear in tag 'INPUT [type=password]'.

What's the issue?

AMP validation error The attribute '[type]' may not appear in tag 'INPUT [type=password]'.

How do we reproduce the issue?

I am creating a show / hide password button and if I set the input type to password, AND add the [type] amp-bind attribute, the AMP validator starts screaming with the above-mentioned error. If I set the input type to text, it works fine.

Code:

<form class="m3" action-xhr="https://example.com" method="post" >
        Password: <input type="password" [type]="toggleType ? 'password' : 'text'" value="password" >
</form>

Which AMP version is affected?

Version 1906191709480

If the format of the AMP document is AMP4EMAIL, this is working as intended. We currently disallow input[type=password] as well as changing input[type] at runtime to prevent potential spam/cloaking.

@Stefany93 Can you share the full page HTML?

[Stefany93]

Sure! https://codepen.io/Stefany93/pen/KjyryP?editors=1000 I made a button to hide / show password field.
I hope you won't disallow it, heh. The type is initially text which is actually better user experience than being initially password but I was wondering if it is a bug. It is working fine. Just not password to text

Ok, this is just an inconsistency for the AMP format. Thanks for the report.
